A practical plug‑in chain designed to add secure locking options when used with a compatible frame lock. The 130 cm length allows the bike to be fastened to a fixed object, preventing thieves from lifting it and moving it elsewhere. The chain connects directly into the frame lock so both the lock and the chain operate with the same key. The hardened steel shackles measure 5.5 mm, and the 10 mm plug‑in pin provides a solid connection. A black polyester sleeve protects the bike’s finish during use.
